UPDATES: Worst mass shooting in US history in Vegas with more than 50 dead and 400 injured

Suspect dead as horrific images are emerging from the mass shooting in Las Vegas, where the death toll has been raised to 'more than 50' with another 400 injured. Ten weapons were found in the hotel room of the 'lone wolf' gunman who shot the crowd from his hotel room on the 32nd floor before killing himself.

More than 50 people have been killed in the deadliest mass shooting in US history after a gunman opened fire on an open-air music festival from the 32nd floor of the Mandalay Bay hotel and casino on the Las Vegas strip.

Police have named Stephen Paddock as the machine gun shooter who opened fire on the crowd at the music festival below.

A further 400 people were injured, the Clark County sheriff, Joe Lombardo, said.

The death toll surpasses the Orlando shooting at the Pulse nightclub in June 2016, when 49 people died.

Police confirmed:

"The Las Vegas metropolitan police department identified the lone suspect involved in the late night mass shooting on the Las Vegas Strip as 64-year-old, Stephen Craig Paddock, a white male from Mesquite, Nevada.

"Paddock opened fire on a crowd of more than 22,000 concert-goers from his hotel room on the 32nd floor of the Mandalay Bay hotel on Sunday evening at approximately 10:08pm.

"The victims were across the street attending the Route 91 Harvest Festival concert when bullets rang out. LVMPD Swat responded to the call, breached the hotel room and found the suspect dead. The Clark County fire department estimated that approximately 406 people were transported to area hospitals and 50 are dead following Sunday evening’s shooting.

"Among the dead is an LVMPD officer who was off-duty at the time. His name is being withheld pending notification of next of kin. There were also two on-duty officers injured, one of whom was upgraded recently from critical to stable condition. The other sustained non-life threatening wounds.

"The Federal Bureau of Investigations is asking for anyone with videos or photos concerning the shooting to call 1-800-CALLFBI or (800) 225-5324. LVMPD and Clark County coroner’s office have set up a hotline for family or friends to report a missing loved one connected to this incident. The hotline is only to take reports on missing people. The number is (866) 535-5654. LVMPD also opened up a family reunification centre at its headquarters at 400 S. Martin L King Blvd in Building B.

"The identification process of all of the injured and the deceased will take time, so authorities are asking the public for patience.

"Anyone wishing to help is asked to donate blood for the injured victims of the Strip shooting. United Blood Services will start taking donations at 7am at two locations: 6930 W. Charleston in Las Vegas or 601 Whitney Ranch Drive in Henderson. UMC will also be hosting a blood drive in conjunction with United Blood Services.

"It will be held at UMC’s Delta Point Building located at 901 N Rancho Lane. There will be updates as to the exact time of the blood drive as more information is available."

Two of those killed were off-duty police officers.

The only suspect, whose motives are unknown, killed himself as a Swat team used a controlled explosion to enter his hotel room on the 32nd floor of the Mandalay Bay hotel and casino.

The gunman was Stephen Paddock, a 64-year-old local man.

Sheriff Joe Lombardo is giving another press conference. He says there is nothing “derogatory” in the background of the suspect, Stephen Paddock.

People were seen running for their lives or lying on the ground as chaos broke out at the scene in the Nevada city.

Witnesses and video recorded rapid fire.

Jackie Hoffing, who lives in Las Vegas, said: “It was hysteria. There were people trampled … I was with my husband. He stayed with me. We jumped walls, climbed cars, ran for our lives. I’ve never run that hard or been that scared in my whole life.”

Desiree Price, visiting the city from San Diego, had blood on her shirt and trousers. “We heard shots like firecrackers,” she said. “I helped someone who was bleeding. Two girls hid behind a car with us right outside the concert. One girl was shot in her leg, the other in her shoulder. It didn’t stop so we all ran – we kept going.”

Police were originally telling people to stay clear of the Luxor resort after a 'black Audi with wires sticking out' was spotted.

There were also reports of shots being fired at the Hakkasan nightclub and the Bellagio has also been evacuated amid reports of a gunman with a rifle.

These are yet to be verified by police but the LVPD are investigating other shootings in other casinos.

Jake Owen, the country music star who played the set before Jason Aldean’s, wrote on Twitter that “gun shots were ringing off the stage rigging and road cases”.

He suggested that the gunman was aiming at the stage at times.

“No one knew where to go,” he added.

The attack took place during the final performances of the three-day Route 91 Harvest country music festival on Sunday night.
